Patent GB-601210-A (GB)
Title: A process for the preparation of esters of fluorophosphonic acids and chlorophosphonic esters
IPC: C07F9/14
Filed: 1943-09-15
Abstract: Fluorophosphonic acid esters are obtained by reacting a chlorophosphonic ester of the formula <FORM:0601210/IV(b)/1> where R is an aliphatic radical, with an inorganic fluoride.  The chlorosulphonic acid esters are obtained by treating an organic hydrogen phosphite of the formula <FORM:0601210/IV(b)/2> (obtained by adding phosphorous trichloride to an alcohol preferably using a solvent, e.g. carbon tetrachloride) with chlorine.  It is not necessary to isolate either the hydrogen phosphite or the chlorophosphonic acid so that the whole of the reactions may be carried out in a single vessel.  In examples (1) to (4) chlorine is passed into the hydrogen phosphite to produce di-isopropyl, diethyl, di-sec.-butyl and di-isoamyl chlorophosphonate; (5) to (11) the chlorophosphonate is gently heated with an inorganic fluoride to produce di-isopropyl, di-ethyl di-sec.-butyl, di-isoamyl, di-(1 : 3-dimethyl-n-butyl), di-(1-carbethoxyethyl) and di-(1 : 3-dichloroisopropyl) fluorophosphonate; (12) phosphorus trichloride is added to isopropyl alcohol in carbon tetrachloride, which chlorinated and treated with sodium fluoride to produce di-isopropylfluorophosphonate; (13) di-sec.-butyl fluorophosphonate is produced as in (12).  Di-isopropyl hydrogen phosphite is obtained from isopropyl alcohol and phosphorus trichloride using ether or carbon tetrachloride as solvent or by direct treatment. Di-(1-carbethoxyethyl) hydrogen phosphite is obtained from ethyl lactate in carbon tetrachloride and phosphorous trichloride. Di-sec-butyl hydrogen phosphite is obtained from sec.-butyl alcohol in ether and phosphorus trichloride.

Title: Apparatus for the remote control of calculating machines
IPC: H01H3/28
Filed: 1959-05-05
Abstract: 869,447. Mechanical calculating-apparatus. ELECTRO - CONTROL - AUTOMATIC G.m.b.H. May 5, 1959 [May 6, 1958], No. 15344/59. Class 106 (1). Apparatus for the remote electrical control of a calculating machine comprises electromagnetic control means adapted to limit the movement of differential actuators normally controlled by keys. As described, for transmission of values from a first calculating machine I, Fig. 2, to a second calculating machine II, Fig. 3, each machine, Fig. 1, has a member 10 attached to each differential actuator 31. Each member 10 has a contact bridge 13 having wipers 36 adapted to move over contacts 0<SP>1</SP>-9<SP>1</SP> and 0<SP>2</SP>-9<SP>2</SP>, Figs. 2 and 3. The contacts 0<SP>1</SP>-9<SP>1</SP> are connected across a potential divider, Fig. 4, to give successively increasing incremental potentials. The contacts 0<SP>2</SP>-9<SP>2</SP> are connected to electromagnets 20-29 having cores 11 which normally project into the path of travel of the members 10. The machine II is prepared for reception by opening a contact 16<SP>2</SP>. If, for example, the digit 7 is introduced in the machine I, Fig. 2, the actuator 31 for that denomination, when released moves with its contact bridge 13 up to the pair of contacts 7<SP>1</SP>-7<SP>2</SP>, Fig. 2, the coils 20-27 being energized over a contact 16<SP>1</SP> as the bridge 13 passes over the associated contacts, so that the corresponding cores do not impede the movement of the bridge 13. The potential for the digit 7 is transmitted via the contact bridge 13 and circuit 15<SP>1</SP> to the input circuit 14<SP>2</SP> of the machine II. The member 10 of the machine II, when released moves up to the contacts 7<SP>1</SP>-7<SP>2</SP> since the coils 20-26 are energized due to the potential difference between the circuit 14<SP>2</SP> and the contacts 0<SP>1</SP>-6<SP>1</SP>. The coil 27, however, is not energized and its core 11 stops further movement of the member 10 and actuator 31. The digit 7 is thus introduced into the machine II. Transmission in the opposite direction may be effected by closing the switch 16<SP>2</SP> and opening a switch 161.

The neon tube may be combined with coloured glass screens to give the port and starboard colours, or the natural light of the neon tube may be used for the port light while for the starboard light the glass of the front 11 or of the tubes may be amber-coloured, or the neon tube may be made to give a blue light by the addition of mercury and used with an amber-coloured screen. A switch may be provided operating in conjunction with the door of the lantern to break the circuit when the door is opened. Reference has been directed by the Comptroller to Specifications 5589/11, 12156/14, 150,957, 237,942, 245,672 and 268,046.
Patent GB-1478761-A (GB)
Title: Thermal imaging system with redundant object space scanning
IPC: H04N5/33
Filed: 1975-04-15
Abstract: 1478761 Infra-red imaging system HUGHES AIRCRAFT CO 15 April 1975 15429/75 Heading H4F Thermal imaging system comprises optics 30-38 directing an infra-red scene image on to an azimuth-scan rotating mirror drum 40 and then via an elevation oscillating mirror 44 to an array of detector elements 48, the electrical outputs of which are connected via individual channels to an identical array of light emitting elements 60 whose light outputs are directed via an elevation oscillatory mirror 64 (mounted on the other end of the pivotally yoke 43 on which mirror 44 is mounted), azimuth-scan mirror drum 40 and optics 66-68 to a viewer or vidicon camera. With this arrangement each detector element views every point in the field of view during each scanning frame period. The detector array 48, Fig. 3, (which is identical to the LED array 60) specifically comprises 18 detectors arranged in six groups each of three detectors aligned in the azimuthal scan direction so that a complete field scan is effected as shown in Fig. 4. At the end of each field scan the elevation scan structure is indexed by 1¢ effective scan lines (fractional relationship between azimuth and elevation cycles) so that the scan lines of the fields are interlaced, and as shown in Fig. 4 four field scans comprise a complete frame scan. Thus during one frame period a number (i.e. 18) of registered pictures each of which is indicative of the thermal energy distribution within the field of view is produced, this number corresponding to the number of detector element and LED pairs. The detector array has a 50% "over scan" since the lower one-third portion of the three detectors of each group is scanned by the same segment of the field of view as the upper onethird portion of the three detectors of the adjacent group (this overlap is not indicated in Fig. 4). The input optics include an objective 30, a focusing lens 32, a boresight prism 34, a field switch lens 36 and a relay lens 38. The output optics comprise lenses 66 and 68, and a reticle pattern 67. The system is such that channel to channel non-uniformity does not cause line to line or region to region non-uniformity, and in addition the resulting image is insensitive to the presence of dead channels. The system is suitable for use with an afocal magnifying system.

Title: Improved manufacture of phthalocyanines
IPC: C09B47/06
Filed: 1936-06-04
Abstract: The process described in Specification 464,126 for making metal phthalocyanines (from phthalic anhydride and other phthalic derivatives, urea and a metal-yielding substance), if desired as modified as described in Specification 464,673 (addition to boric acid), is modified by addition of a substance consisting of or containing an element of Group V or VI of the Periodic System according to Mendel<\>aeef and having an Atomic Number between 15 and 23 or between 33 and 92 each inclusive.  Improved yields are obtained and the reaction proceeds at a lower temperature.  In examples: (1) urea, phthalic anhydride and cupric chloride are heated in presence of a small amount of ammonium molybdate to produce copper phthalocyanine; 3 : 6-dichlorophthalic anhydride similarly yields copper octa (3 : 6)-chlorophthalocyanine; instead of the molybdate there may be used diammonium hydrogen phosphate, tartar emetic or tungstic acid; ammonium molybdate may be used with boric acid; ammonium phosphomolybdate or phosphotungstomolybdic acid are also mentioned; (2) similar to (1) using arsenious oxide.  Bismuth sulphate, ammonium vanadate, selenium, sodium or potassium molybdate, potassium thiomolybdate, molybdenum trioxide and sodium borotungstate are also specified.
